For more detailed information on types of pressure gauges read How to Select Pressure Sensors 1. Differential pressureis measured by reading the difference between the inputs of two or more pressure levels. The sensor must have two separate pressure ports; the higher of the two pressures is applied through the high port and the lower through the lo...
Working pressure range is the maximum allowable pressure at which a system or piece of equipment is designed to operate safely. The extremes of this range should be determined in accordance with th...Dial diameteris the diameter of the gauge. The dial size is usually determined by the readability requirements; larger for remote reading and smaller where the gauge is close to the operator. Gener...Accuracyis defined as the difference (error) between the true value and the indicated value expressed as percent of the span. It includes the combined deviations resulting from the method, observer...Vacuum rangeis the span of pressures from the lowest vacuum pressure to the highest vacuum pressure (e.g., from 0 to 30 inches of mercury VAC).Scale Type
The scale is located on the face of the analog pressure gauge. Scale can help determine accuracy, with smaller scales leading to more accurate readings. The face of the gauge can have a single or dual scale. 1. Single scalepressure gauges have one scale (one set of units) on its face. 2. Dual scalepressure gauges have two scales (two sets of units) on its face. This is commonly seen in compound pressure gauges.
Scale Units
Most pressure gauges measure positive pressure in psi, and negative pressure is frequently measured in inches of Hg.
For more detailed information on sensor technologies read How to Select Pressure Sensors. 1. Microelectromechanical systems (MEMS) are typically micro systems manufactured by silicon surface micromachining for use in very small industrial or biological systems. 2. Vibrating elements (silicon resonance)use a vibrating element technology, such as sil...
Analog pressure gauges should be selected considering the media and ambient operating conditions. Gauge selection should take into consideration the corrosive environment in which it is to operate. The media being measured must be compatible with the wetted parts of the pressure instrument. Improper application can damage the analog pressure gauge,...
Common features of pressure gauges include adjustable pointers, maximum and minimum pointers, adjustable and stationary set hands, throttling devices, and electric contacts. 1. An adjustable pointerhas adjustment to zero the pointer via screw or knob. 2. A maximum and minimum pointerindicates the maximum or minimum pressure attained. 3. An adjustab...
May 30, 2023 · Be sure to consider what your gauge’s operating pressure will be, and what maximum pressure your system will reach. You want your gauge’s operating pressure to lie within the middle third of the dial, and your range to be higher than your system’s maximum pressure.
The Constant Pressure by Franklin Electric is a website designed to inform homeowners of water pressure problems in their homes and how a constant pressure system works eliminating low pressure in water wells.
Jan 24, 2023 · A pressure gauge is an instrument that measures the pressure of a gas or liquid relative to the atmosphere, a vacuum, or the difference between two points. Understanding the pressure gauge meaning helps in comprehending the instrument's function and significance in various applications.
